Do pineapples ripen faster if they are put upside down?

A pineapple does not ripen after it is picked. As a result, tricks to ripen the fruit faster, such as placing it upside down, are not effective.

The ripeness of a pineapple cannot be determined by the color of its external shell, its overall size or the ease of pulling down its leaves. To ensure that a pineapple is ripe, the buyer should select one that is plump, firm and fresh-looking with bright green leaves. It should have a fragrant smell, especially near the bottom. Its shell should not have any soft or brown spots. It stays fresh longer if stored in the refrigerator.
